"WebbSkewness can be shown with a list of numbers as well as on a graph. For example, take the numbers 1,2, and 3. They are evenly spaced, with 2 as the mean (1 + 2 + 3 / 3 = 6 / 3 = 2). If you add a number to the far left (think in terms of adding a value to the number line), the distribution becomes left skewed: -10, 1, 2, 3. " - Shape of distribution graph

WebbSome data sets have nearly all their frequency values clustered to one side of the graph. This frequency distribution shape is known as logarithmic. A common example of this in real life is found in distributions of wealth and income, with large numbers of people at the bottom but extreme outliers extending the tail to the right. This ... Webb2 maj 2024 · Key Takeaways. Skewness is a statistical measure of the asymmetry of a probability distribution. It characterizes the extent to which the distribution of a set of values deviates from a normal distribution. Skewness between -0.5 and 0.5 is symmetrical. Kurtosis measures whether data is heavily left-tailed or right-tailed.
